l0 laying wooden' sleepers in the surfaces oi concrete floors. y

Figure l is a horizontal View of a iloor in the course of Construction, showing the temporary floor,4 the brackets, and the sleepers located thereon, embody- Fig. 2 is a perspective View of a part of a sleeper and of its supporting brackets. Fig. 3 is a horizontal. sectional view of the concrete floor construction embodying my invention.

In making concrete iioors, it has been customary to 20 spread a layer of concrete upon the temporary iiooring, to allow this concrete to harden, then to lay the wooden sleepers, which afford a nailing surface, upon this first layer of concrete, and then to iill in eround the sleepers with another layer oi concrete'.

1n my construction 1 secure rows of brackets, A, to f the sleepers, C, by means oi nails, c. Then l secure the brackets to tire flooring, B, by lucani-i o nails, a. Then I iill in about the brackets and about the sleepers, C, with concrete, D, leaving the upper face oi` the sleepers exposed.

it is seen that the process of constructing the iioor with my supporting brackets for the sleepers, is a continuous one, that is, that the concrete is laid at one operation. Besides'siinpliiying the method of iorming the ilooring, the brackets distribute the strain due to the nailing oi the permanent floor te the sleepers, over a greater area of concrete and thus prevent any tendency to crack in the saine in securing the pernutrient floor in place. f

What I claim is:

In n concrete floor in the course oi.' construction, `the
